I believe the correct word was “trunk”Which I knew, which is why I didn’t see my own typo.Gah. Thanks guys.

Russell, I believe you accurately repeated what Parker was reported to have said – I too wondered , and searched , and could only find main sewer truck and this comment by a Paul Stockley about the ethics of correcting quotes:

Example 1:A reporter mistook a technical term ‘trunk’ (meaning main route) as ‘truck’, and this error was published. Correct it thus when quoting[*]:"Our main sewer [trunk] is seriously munted … I believe that is the technical term."

But, then again, I wouldn’t put it past Bob, our ‘Great Communicator’, to have got it wrong in the heat of the moment…
